CLARIFIER.

To all whom it may concern:

Be it known that I, OTTO E. SZEKELY, a citizen of the United States, and a resident of Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Clariiers, of which the following is a specilication.

My invention relates to an improved cleaning device or clarifier particularly adaptable for cleaning air before its delivery to the explosive mixture of a gas engine.

The object of the invention is to produce a simple, inexpensive and etlicient air cleaning device which can be readily applied to the end of an air intake conductor leading to the carbureter where the explosive mixture for the engine is formed. Another object is to provide such construction that the cleaning device can be readily taken apart in order to discharge accumulated dirt extracted from the air during operation of the cleaning device.

. On the accompanying drawing I show a device embodying the features of my invention and illustrating the manner of its connection for service in association with a gas engine. On the drawing* Figure 1 is a side elevational view of va gas engine with the clarifier applied,

Fig. 2 is an endview,

Fig. 3'is an enlarged sectional view on plane 3*3, Fig. 1,

Fig. 4 is a sectional View on plane 4 4, Fig. 3,

Fig. 5 is anY enlarged vertical diametral sectional view of the clarifier, and A,

Fig. 6 is a sectional view on plane 6 6, Fig. 5.

The cleaning device or clarifier comprises a. cylindrical body or barrel 5 having a coupling or elbow 6 extending from the conical top 7 secured thereto. Suspended within the body 5 and spaced away therefrom is the cylindrical hood or inverted cup 8 held in place by a diametral ycross bar 9 secured to the upper end of the lbody 5, this hood or cup terminating a distance'above the lower end of the body 5. The bottom 10 has the iiange 11 for intimately receiving the lower end of the body 5 and has the lower cylindrical flange 12 in which is secured the tube 13 of smaller diameter than the hood 8 and extending upwardly therein -to within a serial No. 189,050.

short distance of the top thereof, with its upper end covered by a comparatively coarse screen 14. Surrounding the lower end of the hood 8 and extending therefrom to the Specification of Letters Patent. Patented May 28, 1918.

Application filed August 31, 1917.

lower end of the body 5 is the cylindrical v finer screen 15. The bottom 10 with the tube 13 extending therefrom forms an annular oil receiving space 16, suiiicient cleaning iiuid O, such as oil, being poured into this space so that the level thereof will be some distance above the lower end of the screen 15.

lIn Figs. 1 and 2, 17 represents a. gas engine with which is connected the intake manifold 18 and the exhaust manifold or pipe 19, a carbureter 20 being connected with the intake manifold. The cleaning device or clarifier can be connected at its upper end directly with the air inletl of the carbureter, but preferably the air, after being cleaned, is heated before delivery to the carbureter. Such heating can be -readily accomplished by surroundingl a section of the exhaust pipe 19 by a heating jacket 2l having the inlet end 22 and the outlet end connected withthe carbureter by a pipe 24.

The operation is now apparent. When the engine is operating the suction impulses will cause air to be drawn into and through the tu'be 13 of the cleaning device, this air flowing through. the coarse screen 14 at the inner end of the tube so that the heavier solid particles and dust or dirt are prevented from entering the device. The air then travels downwardly between the tube and the hood 8 and then through the fine screen 15 and upwardly between the hood and the body 5 and through the outlet elbow into the heating jacket 2l where it is heated before reaching the carbureter. Any solid particles which pass through the coarse screen 14 will be intercepted by the fine screen and will drop into the Huid C) to be retained thereby., The suction effect created within the clarifier by the engine suction impulses will act on the iuid and will agitate it suiiiciently to cause it to film over the fine screen so that any solid particles or impurities in the air must pass through the iuid lm to be attracted and retained thereby and washed down into the body of the uid.

After a period of use of the clarifier its botbottom :tor said body, a

ily withdrawn and the dirty duid discharged and clean duid poured in. Alfter removal ot the bottom the screens are readily accessible and can be thoroughly cleaned.

l do not desirey to be limited to the exact construction and arrangement as mdiiications can probably be made which would still come within the scope ot the invention.

l claim as` follows:

l. A cleaningdevice comprising a tubular body, means -lier connecting the upper end of the body'with the end ot a pipe, a tube ot less diameter than said body extending upwardly through the bottom and communicating at its lower end with the atmosphere, a hood suspended over the inner end of the tube withits sides intermediate those of the tube and the body, a screen covering the inner end of saidtube, and another screen depending from the lower end of said hood whereby the incoming air must travel in a roundabout way and must be screened before leaving the device.

2. lln a device tor cleaning the air for explosive mixtures for gas engines, the combination of a body part adapted for connection at its upper end with the air intake for the engine, a bottom for said body part, an open.- ended tube extending upwardly through said bottom and into the body part,

cleaningl fluid in said body part at the lower end of said body part surrounding said tube, a hood suspended over the inner end of said tube with its sides depending between the tube and the body part and with its lower end terminating a short distance above said cleaning duid, and a screen depending from said yhood and extending a dist-ance into said fluid to bridge the gap between said hood and fluid whereby air traveling through said tube and hood must pass through fluid splashed onto said screen to be therebycleaned before reaching the body part and the explosiwel mixture. I

3. A'cleaning'device ot the class described comprising, a cylindrical body, a tubular coupling head onsaid body for connecting it with an air intake conductor, a bottom for said body, a tube of less diameter than said body extending centrally through said bottom and into the body, said tube and bottom forming an annular reservoir, cleaning fluid in said reservoir, a dellector hood suspended over the inner end of said tub-e with its cylindrical sides depending between the tube and the body and terminating above the duid, and a cylindrical screen depending from the lower end ed said hood into said duid to be in the path ot thepair'to clean it before it reaches the air intake conductor. e'. A cleaning device oi the class described comprisingk a cylindrical body, a tubular coupling head on said body for attaching it to the air Yintake conductor of a gas engine, a bottom for said body, a tube of lem diameter than said body extending upu wardly through said bottom into the body,

forming an annularV said tube and bottom reservoir, cleaning fluid in said reservoir, a hood suspended with its base above the inner end of the tube and with its cylindrical sides depending between the tube and body and spaced theretromLa screen covering the inner end of said tube, and a cylindrical screen depending from the lower endl of said device of the class de- Y said body extending upwardly through the Y,
